By the title, you can probably guess what I’m proposing, but alas. In this method you swap pieces into locations next to pieces with the same color. For example on 5BLD, you would put the wings next to the midges, and then solve like a 3x3. Similarly, on 4BLD you could just swap to the piece most clockwise or something of the like. Center memo and exec would be the same.
